| Feb 21 at 14:52 | comment | added | Christian Remling | It's of course false as written (compare Denis's comment) because it doesn't scale right: $\langle x, A(\lambda x) x\rangle \simeq -\lambda \|x\|$ as $\lambda\to\infty$ | |
| Feb 21 at 8:09 | comment | added | Denis Serre | Are you sure of the formula ? This matrix sounds familiar to me, but only if the exponents $1/2$ and $3/2$ are exchanged. | |
